Sounds like https://en.wikipedia.org/wiki/Time_dilation https://en.wikipedia.org/wiki/Time_dilation by moving at high relativistic speeds close to the speed of light? Even more fascinating for me is the concept of a https://en.wikipedia.org/wiki/Nuclear_lightbulb https://en.wikipedia.org/wiki/Nuclear_lightbulb in the context of https://en.wikipedia.org/wiki/Vimana https://en.wikipedia.org/wiki/Vimana s Imagine they had a https://en.wikipedia.org/wiki/Metamaterial https://en.wikipedia.org/wiki/Metamaterial which would have enabled that. I mean withstanding 22.000°C while being transparent to hard ultraviolet. And some sort of 'ultravoltaic' cells behind that... ...while at least some texts speak of those things as full of crystals and mirrors as part of their engines and on board power plants.
